MACHINE FOR BLOWING GLASS.

SPECIFICATION forming* part 0f Letters Patent'N 7 03,32 5, dated June 24, 1902.

Application filed October 18, 1901. Serial No. 79,161. (No model.)

T0 all whom, it pta/y concern:

Be it known that I, ORRIN E. WALTON,a citizen of the United States,residing at Sycamore, in the county of Vyandot-andState of Ohio, have invented new and useful Improvements in Machines for Blowing Glass, of which the following is a specification.

My invention relates to improvements in machines for blowing glass; and the objects are to improve and simplify the existing art by providing improved means for mechanically actuating the blowpipe in its requisite movements and to provide novel means for carrying the blowpipe from the shaper to the furnace, where the material is -reheated and swung in the pit. This operation'is repeated until the cylinder is swung out the required length.

With these objects in view my invention consists in the novel construction of parts and their arrangement or aggroupment in operative combinations, as will be hereinafter fully described and then particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings, to be taken as a part of this specification, and wherein- Figure 1 s a plan view of the complete machine, wherein the cylinder of glass is 'indicated in dotted lines and showing the shaping-pot as turned to stand in the `pathof the blowpipe. Fig. 2 is a side Viewin elevation, partly in section, also showing the shapingpot and indicating in dotted lines its position when turned aside from the path of the blowpipe. Fig. 3 is a detail view, partly in central section, of the means for rotating the blowpipe, also showing the valve and the airconduit leading to the blowpipe. Fig. 4 is a central vertical section through the shapingpot. Fig. 5 is a detail view, partly in section, of the shaping-pot, showing the supportingstandard with spiral groove.

Referring to the drawings, A designates a substantial supporting-frame erected over the' pit and of such length and width as may adapt it for the purposes intended and to support the mechanism for operating the blowpipe. On this supporting-frame is laid and secured a track 1 1, the rails of which support a car, hereinafterdescribed. The floor of the frame is open for the greater part of its length to aord room for the movements of the blow- `pipe. For a proper distance at the front portion of the Hoor of the frame the track consists of parallel rack-rails 2 2, in which the teeth of the large front Wheels of the car engage. A car is provided which is movable lback and forth on these tracks. This car is made, preferably, ofv suitable pipe-iron bent into loops 3 4, the bars of which are parallel with each other, and on the end bars thereof are journaled proper Wheels 5, adapted to run on or inside of the plain rails of the track, as indicated in the drawings. At the front of the car the side bars of the car-frame extend vertically, as at 6, and are connected by a cross-bar 7, constituting a shaft on which are journaled the large front Wheels 8, the cogs or teeth of which engage the track-racks and carry the car back and forth on the track. On the car-frame is secured a door or platform 9, having an opening l() to provide room for the swing of the blowpipe and access to the shaping-pot and pit, and on this floor or platform the workman stands during the operation of the machine. On the floor 9 are mounted -and secured oppositcly-arranged supports 11 12, formed with bearings in their upper ends, in which is journaled a shaft 13, on which is mounted a sprocket-wheel 14, carryingachain15,arrangedaboutasprocket- `wheel 1G, journaled on the fixed shaft 7, the hub of the wheel 16 being rigidly connected to the car-wheel 8, so as to turn therewith.

`On the shaft 13 is fixed a hand-lever 17, by

the car in either direction to reciprocate the blowpipe to carry the cylinder into and out of the furnace. The other wheel 8 on the shaft 7 is made to revolve on the shaft by its engagement with the rack.

On the platform of the car are mounted opposite standards or benches 18 19, having bearings in their upper ends, in which is journaled a shaft 20,-having a diametrical opening 21 therethrough, wherein is revolubly placed a sleeve 22, having interior screwthreads at one end and an annular fiange at the other, and in this sleeve the screw-threaded end of the blowpipe engages and is held,

substantially as seen in Fig. 3 of the drawings. On the projecting end of the sleeve 22 is mounted the hub of a beveled pinion 23, which meshes with a counter beveled pinion 24, mounted loosely on the shaft 20, which pinion 24 is integral with a pulley 25 on said shaft. The pulley, with the beveled pinion 24, is loosely mounted on the shaft and the two have a limited sliding movement on the shaft in order that they may be thrown into and outy of engagement with the pinion 23, so that the blowpipe may be rotated as desired. The beveled pinion 24 is held in operative engagement with the pinion 23 by means of an expansive spring 26, arranged on the shaft 20, and the sliding movement is attained by means of a clutch-lever 27, fulcrumed on a support extending from the shaft, as shown in Fig. 3 of the drawings, and the engagement and disengagement of the lever being effected by means of a notched plate 28 and thu mb-bar 29.

To the shaft 2O is secured a valve box or chamber 30, provided with a suitable valve 3l, manipulated by means of a hand-wheel 32 or equivalent means, and from the valve the air is admitted to the blowpipe through a conduit opening into a nipple 33, loosely projecting into the sleeve 22, by which it communicates through the sleeve into the blowpipe and cylinder, as shown in Fig. 3 of the drawings. Projecting in opposite direction to and in the same horizontal plane as the blowpipe and secured to the shaft 2O is a lever 34, by which the blowpipe can be turned or swung on its bearing during the blowing, for a purpose well known in the art. A weight 35 is slidably mounted on the lever 34, whereby the weight of the blowpipe, with the attached material, may be counterbalanced, so that the power necessary to swing the pipe is reduced to a minimum. The requisite force to expand the cylinder consists of compressed ai r let through the valve and blowpipe through a fiexible pipe 36, leading from a compressed-air source located at some con,-

,. venient point adjacent to the machine.

To rotate the blowpipe, I erect opposite standards 37 38 at the sides of the frame and in suitable bearings at the tops thereof journal a shaft 39, on which is mounted a pulley 40, on which is a belt 4l, extending to and arranged ou a pulley 42, mounted on a shaft 43, supported by an arm or rod 44, loosely sleeved on the shafts 39 and 43. From a pulley 45 on the shaft 43 extends a belt 46, arranged at its lower end on the pulley 25 on the shaft 20, as shown in Figs. 1 and 2 of the drawings.

Loosely hung on the shaft 43 is a rod 47, having an aperture or eye 48 at its lowerI end, throughA which the shaft 2O loosely passes.

A pulley 49 is mounted on the shaft 39, which by suitable belt connection communicates with the power.

It will be perceived from the foregoing description that by the belt connections the blowpipe is rotated on its longitudinal axis and that the jointed supporting-arms maintain at all times the tension of the belts as the nates a substantial standard formed with a.

spiral groove 51, and 52 the shaping pot formed with avertical hole 53, in which the standard fits so that the shaper may turn thereon and be swung in a horizontal plane. It is also essential that the pot shall be movable vertically, and to accomplish this a'pin 54 is let through the wall of the body so that its end projects into the spiral groove 51, whereby when the shaper is swung around the pin travels up the spiral and carries the shaper upward. The shaping pot proper comprises a body 55, having a chamber 56, into which water is admitted through a pipe 57. The upper surface of the body is dished out, as at'58, to receive the water that may run back from the pipes. The pot itself, 59, is supported above this concave or dishedou't base. Rising from base and projected vertically through the rim of the pot are a series of pipes 60, having perforations 61 in the part extending above the pot. Revolubly mounted on each pipe is a shell 62, of larger diameter than the pipes, having closed upper ends and open lower ends, so that the water ascending in the pipes may be thrown against the inner face of the shells and render them cool and escape through the lower open ends of the shells. By making the shells 62 revoluble on their bearings the liability of fracture of the cylinder is lessened and at the same time they constantly present a cool surface to the revolving cylinder. A drain-pipe 63 is provided to carry the Water from the lower basin of the shaping-pot.

The operation of the machine may be stated as follows: The workman mounts the floor of the car, the main shaft and the connections being in motion, and, as may be, the clutchpinion in or out of engagement with the pinion on the blowpipe. The shaft carrying the blowpipe is then so turned as to carry the pipe to horizontality. The lever 17 is actuated to run the car toward the furnace F and bring the blowpipe through to extend through the opening o in the furnace for the purpose of heating the material, the pipe being rotated by the rotating mechanism. The

heating being accomplished, the car is run back, the blowpipe swung in the pit and tipped or tilted, with the charge, into the shaping-pot, and rotated as may be required. The blowpipe, with the cylinder, is then IOO IIO

swung into horizontal position, the car is run forward, and a second heating made, and this operation may be repeated as often as required. During the operation described the air is let through the valve and blowpipe to inflate the cylinder. The subsequent processes and manipulation of the cylinder form no part of my invention, and being well known in the art require no description.
